Bees get hooked on harmful pesticide – study
Bumblebees acquire a taste for food laced with a pesticide known to harm them, according to a study suggesting the chemicals pose an even greater threat to pollinators than previously thought.
In experiments, researchers showed that bees initially put off by sugar water containing neonicotinoids – the most widely-used class of insecticide worldwide – soon started seeking them out to the exclusion of untainted food. The findings were published on Wednesday in the journal Proceedings of the Royal Society B.
Neonicotinoids, earlier research has shown, disrupt the ability of bees to reproduce and lower their resistance to disease. Global bee populations are on the decline. And in Southwest China they have become so rare that fruit plantations are no longer being pollinated. Farmers are now doing it themselves.
